An outbreak of highly-contagious norovirus gastroenteritis in southeast Queensland has spread west to Ipswich to infect more than 50 nursing home patients.

Queensland Health is trying to contain the outbreak, which had already hit 18 patients at the Caloundra hospital and seven at the Nambour hospital on the Sunshine Coast.

Authorities say it has now spread to 11 patients and 11 staff at Ipswich Hospital, west of Brisbane, and one patient and 13 staff at the nearby Boonah Health Service.

The illness has also struck 55 patients and 14 staff at an Ipswich nursing home, which has since gone into lockdown.

Affected areas of Ipswich Hospital have also been isolated.

The spread of norovirus comes as Queensland Health battles an E coli outbreak, originating from animals at Brisbane's Ekka Show last month.

Health authorities are responding to a measles outbreak along Australia's east coast, believed to have been caused by infected passengers travelling between Queensland, NSW and Victoria.

Queensland Health says a fourth case of measles in as many weeks in the state has been reported.
